RUBBER'BOOT OR SHOE.

SPECIFICATION forming part of Letters Patent No. 687,578, dated November 26, 1901.

I Application filed March 11, 1901. Serial No. 50,717. (No model.)

To all whom it may concern:-

Be it known that I, AUGUSTUS T. Senna- MERHORN, a citizen of the United States, residing at Newhope, in the county of Bucks and State of Pennsylvania, have invented new and useful Improvements in Leather-Bottom Rubber Footwear, of which the following is a specification.

My invention relates to certain new and use ful improvements in leather-bottom rubber footwear, and has for its object to provide an improved manner of securing the leather sole to the rubber upper, so that the boot or shoe containing my improvement will be perfectly water-tight and may be repaired at any time by the addition of a new outer leather sole or heel, or both, in the same manner as prac-.

ticed in connection with ordinary leather boots and shoes.

Other objects of the invention relate to certain details of construction.

I have illustrated the invention in the accompanying drawings, in which Figure l is a plan view of the inner leather sole or welt-sole, and Fig. 2 is a section of the same. Fig. 3'is a plan view of the outer rubber sole, and Fig. 4 a section of the same. Fig. 5 is a plan view of these two soles after they have been sewed or quilted together, and Fig. 6 is a section of the same. Fig. 7 is a plan View of the same parts, showing a sheet of rubber laid over the stitching of the rubber sole; and Fig. Sis a section of the same. Fig. 9 is a section through the forward portion of a shoe, showing the parts illustrated in Figs. 7 and 8 applied to a rubber upper.

Fig. 10 is a similar view showing the outer leather sole secured to the welt-sole, and Fig. Fig. 11 is a side view of a complete shoe constructed according to my invention.

Referring now to the drawings, the numeral 1 indicates the rubber upper of an ordinary rubber boot or shoe; 2, the inner sole thereof; 3, the rubber sole; 4, a leatherwelt-sole secured to the rubber sole 3, and 5 the outer leather or wearing sole sewed, pegged, riveted, or otherwise secured to the welt-sole 4. In proceeding according to my invention I first secure the leather welt-sole 4 to the outer rubber sole 3 by sewing or quilting the two together, a stay-strip 6, of fabric, being preferably first applied around the upper side of the sole 3 to receive the outer line of stitch* ing 7, extending around the sole adjacent to the margin thereof. This'outer row of stitching is sufficiently removed from the edge of the sole to leave a marginal portion 8 of the rubber sole to be subsequently utilized in securing said sole to the upper of the boot or shoe, and a similar portion 9 of the leather welt-sole, to which the leather sole is adapted to be secured, preferably by stitching. The stitching or quilting of the welt-sole to the rubber sole 3 is done while the latter is in an unvulcanized condition. A sheet 10 of unvulcanized rubber, preferably of a higher grade than that of the rubber sole proper, is now placed over the stitching on the upper side of said rubber sole, as shown in Figs. 7 and 8, and said solo is then secured in the ordinary manner to the upper 1, as shown in Fig. 9. The shoe is now subjected to the vulcanizing process, as a result of which the sole 3, with its marginal portion 8, will be firmly united to the upper and the welt-sole 4 to the sole 3. While rubber will adhere with great firmness to leather when vulcanized thereto, the union is of course not so tenacious aswhen rubber is vulcanized to rubber. I therefore stitch or quilt the welt-sole 4 and rubbersole 3 together, as stated, and subsequently vulcanize, the combined effect being to produce a very strong union between these two soles. The projecting portion 9 of the sole 4will now form the welt proper, as clearly shown in Fig. 9, and to complete the shoe the leather sole 5 is secured to the welt 9 by one or more lines of stitching 11. The complete shoe will now have the appearance represented in Fig. 11.

It will be readily seen that in securing the welt-sole to the rubber sole and the leather sole to thewelt-sole none of the stitching passes to the interior of the shoe, and therefore no apertures are made which could subsequently cause the shoe to leak. The sheet of rubber 10, which is vulcanized to the top of the rubber sole, covers and closes all apertures made in the rubber sole by the stitching. This sheet is very thin and does not add appreciably to the weight or bulk of the shoe. It will further be seen that when the sole 5 wears out it may be removed and a new solo stitched to the welt 9 in the same manner as practiced in half-soling an ordinary leather shoe. The sole 5 can of course be pegged or riveted to the welt-sole; but I pre fer the stitching for ordinary wear.

Having thus fully described my invention, what I claim as new is= 1. A rubber boot or shoe having a rubber sole provided with an upturned marginal portion vulcanized to the upper, a leather weltsole vulcanized to said rubber sole and a leather wearing-sole secured to said welt-sole.

2. A rubber boot or shoe having an outer rubber sole vulcanized thereto, a leather weltsole vulcanized to said rubber sole and having a marginal portion projecting beyond the same, and an outer leather or wearing sole stitched to said projecting portion.

3. A rubber boot or shoe having an outer rubber sole vulcanized thereto, a leather weltsole stitched and vulcanized to said rubber sole and having a marginal portion projecting beyond the same, and an outer leather or wearing sole secured at its edge to said projecting portion.

4. A rubber boot or shoe having an outer rubber sole vulcanized to itsupper, a leather welt-sole stitched to said rubber sole and having a marginal portion projecting beyond the same, a layer of rubber covering said stitches and interposed between the rubber sole and upper, and an outer leather or wearing sole secured at its edge to said projecting portion.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
